Outstanding lecture sir,this is the most simplified way you explained one can understand the whole thing in a 22 minutes version. Thanks for that please keep doing same good work
Thank you Sir! I have never understood this topic at all before , this video has magically changed that !! have never come across such a simple way of explaining this .. Thank you so much Sir
Nice effort. Appreciate. Would you like to comment for case when generator is on droop and other generator is without droop (asynchronous) on the same network, how asynchronous generator works when there is a network frequency deviation. Will asynchronous gen. start changing its load to maintain its speed ? Specially considering the island network, where too much frequency deviation cannot be afforded (to avoid triggering of load shedding due to frequency protections).
Assume that after paralleling, two generators are sharing a particular amount of load. There is no Power management system to respond to changes that take place .Or we can assume the PMS is on manual. Under this scenario, If one generator's governor has a droop and the other's is in isochronous mode, any CHANGE in load will be taken up by the generator with isochronous governor. If the other generator has to shed or pickup load, its frequency has to change. But the isochronous governor will maintain the frequency at the same (present value). The load on this generator can change and still the frequency will be same. This will mean that any change in load will be picked up by the generator, with the governor having zero droop. This is the main principle by which many generators deliver power to a large grid. Since the grid can be treated as isochronous, if a large load comes on or goes off, its effect on individual generators will be minimal and shared.
Thanks for very good explanation sir. I have a doubt, During parallel operation of alternators, alternator 1 is running, alternator 2 is started now going to parallel with alternator 1 before closing the circuit breaker or before taking the load to alternator 2, how does the speed reduces in the droop curve? Could you give me a answer sir?
I have a question, when decreasing the generator 1 speed in 11:00 doesn't that mean generator 1 have different frequency then generator 2 at 600kw. U did mention that generator run in parallel need to be in the same frequency.
hi i have a question i have MQ Whisper 25 kw it was working fine but one day start to drop the rpms and work fine wit out load the minute you put some 2-3 kw load it starts going up and down and it go off if anyone knows what is going on i be happy to try fix it
Sir, if one generator is running with 200kw and other 500kw then what will be the droop setting of both the generators?...droop of 200kw is more and 500kw is less?
Droop setting decides the slope of the droop line. If two alternators with same power rating also have the same droop setting, the angles will be same. During parallel operation, WE CAN RUN AT ANY SHARE OF LOAD. If droop angles are same, and with manual control ( PMS on manual) ANY CHANGE in load , will affect both alternators equally. If the angles are not same, GREATER CHANGE in load will occur in the alternator with a LOWER droop angle. IF two alternators have DIFFERENT Capacities and are running in parallel, the droop angle of the LOWER Capacity alternator CAN be set higher so that there will be a less CHANGE in load on this alternator.
Droop means- When load increases, the speed setpoint is decreased and when load decreases , the speed setpoint is increase? Please can someone help me.
Droop setting means that ,when two or more generators run in parallel ,at that time to maintain the same speed and electrical frequency. When load is increased generator shaft speed will tend to decrease and droop setting will maintain the speed ,it will not allow to decrease and when load is reduced at that time shaft speed will try to increase and then droop setting will decrease by reducing the oil to control valve servomotor. So the purpose of droop setting to maintain shaft speed when parallel operation.
Sir thanks for video but i have one doubt which governer is isochronos generator or main engine?? According to u with zero droup gov is isochronous and this implies that gen gov cannot be isochronous coz of droup but till now i have heard that gen gov is isochronous coz we need to keep frequency constant. Plz clear this sir which one is isochronous???
Both governors can be run in any mode. Assuming the main engine is single , there is no need for droop. However a small droop setting can be included to make it less sensitive. Alternators which are intended to run in parallel should have governors with droop. It will be more correct to say that an alternator governor has a narrow speed range while a main engine governor will have a much wider range.
So generator governer is assumed to be isochronous coz both have droop for some reason so idealy non of them is run in isochronous mode and generator have narrow range. ??????
@@blmaan9299 A ship's power plant is a good example to understand the principle. A ship typically has three alternators. All the alternator governors typically have a droop setting of about 2%. When ever a generator runs alone, due to the droop, as load increases (or decreases) the frequency will come down (or go up). The engineer will adjust the speed setting of the governor and bring the frequency back to normal. Otherwise the power management system will do this. When the PMS is doing the adjustment , the frequency will remain constant when load changes. This is due the action taken by the PMS. If the droop setting is changed to zero, the frequency will not change when load changes and the Engineer will not need to intervene. However the droop is not changed to zero as a normal practice.

Outstanding lecture sir,this is the most simplified way you explained one can understand the whole thing in a 22 minutes version.
Thanks for that please keep doing same good work
Best lecturer HIMT ever had.
Good explainations...put it simple, the governor with lower droop settings will have bigger change in load during load fluctuations.
Thank you sir.. Respect from Bangladesh.
Thank you Sir! I have never understood this topic at all before , this video has magically changed that !! have never come across such a simple way of explaining this .. Thank you so much Sir
Thank you..Respect from Ethiopia a very good explanation about droop settings
Great lecture, is realy hard to fund goo info on droop control even in power engineering books that i have read.
Thank you Sir, Your video Cleared all the concepts regarding droop and operation of generator accordingly.
Great Video Sir, explained with each and every point in detail. Thankyou Sir for this video.
please upload more videos like these for the benefit of all.... really appreciate ..thanks
Only person why I choose himt everytime
Great video wished I could understand better... guy's the boss
Thank you Professor. Really helpful.
Best...video for drooping 💯
Thank you sir ... very clear explanation ... kindly post more videos
Thanks a lot Sir. Finally i understood it!
This sir passed away..RIP
Sir,
Thanks for uploading.
Please upload more videos
🙏 Many thanks to you sir, for this video.
Very nice video sir best understanding contents... Sir please upload videos of emf equation for alternators, transformer and motors
Very good explanation!
Thanks sir...please upload more videos about alternator
BEAUTIFULLY EXPLAINED! THANK YOU!

i love ur lecture
Sir is it not possible to sync isochronous dgs? But most of the new dgs are isochronous only.why DG having droop will take more load?
Simply Superb
What is the formula for calculating frequency if droop is 4 % and operating at 50 hz and load is increased by 25%.?
Can u make version on generator protection,and motor protection sir
good explanation sir thank you
Cargo oil pump turbine is which type of governors
Isochronous?

what language is this video in?
it would be very nice if you can explain in english, Sir
?????
omg, i can understand english
audio is terrible and I Cannot understand his english man. I wish there were more quality videos about this on youtube!
it would be superb if you add english sub to the video
👍👍👍
Which course is this sir? Preparatory course?
Yeah. This is MEO Class II Preparatory Course
